Light-weight access control scheme for XML data

In this paper, an adaptable light-weight access control scheme is proposed for an evolutionary computing environment. The existing access control environment relies on the server to solve security problems. The current environment has become almost distributed and ubiquitous. This change has spawned the need for light-weight access control by clients, which have a resource-limited environment. Existing studies using role-based prime number labeling (RPNL) are limited by the scalability of the prime number. The problem of scalability of the prime number was addressed with the use of the strong point of RPNL and implementation of persistent XML labeling and efficient query processing. The proposal has the advantage of having an adaptable access control scheme for an existing XML labeling method. We showed the efficiency of the proposed approach through experiments.
